<br />~';f <br /> <br />PROPOSED PillIPING REGIHENS <br /> <br />The preceding analog m~del prediction analyses clearly show <br />that if no counter measures were undertaken QY United states, <br />the pumping from tl1e Sonora Nesa ,;ells l,ould have adverse <br />effects on both Yuma Nesa and Yuma Valley ground,;ater sources. <br />An alternative under eonsideration for the protection of United <br />States "ater resources "auld be to intercept groundliaters be- <br />fore they reach Hexico by the installation and pumping of wells <br />in the southern part of Yuma Nesa. Al though l,"ells could be <br />located an~"here south and east of the Colorado River, it was <br />considered to be desirable to place such l;ells in the southern <br />part of Yuma Nesa and in the southern half of Yuma Valley. The <br />locations of proposed ",ells are shown on Figure B-7; 10 ",ells <br />along the main' gravity drain in Yuma Valley to pump 50,000 AF/yr <br />and 40 ",ells in southern Yuma Nesa, spaced at one mile intervals, <br />to pump 150,000 AF/yr. This'layout and design ,>,as prepared by <br />the Yuma Projects Office, Bureau of Reclamation. The proposed <br />well construction details and conveyance canals, including cost <br />estimates, are given in a report prepared by the Bureau of <br />Reclamation. <br /> <br />The singular effects of several pumping regimens "ere deter- <br />mined ~vi th the analog model by the U. S. Geological Survey. <br />The results of these studies are revie1.:ed as follm;s. <br />
